The present disclosure relates to organometallic complexes and electronic devices containing the complexes. The complexes have the formula MYnZ, where n is 1 , 2, or 3; M is a metal in a +2, +3, or +4 oxidation state, Y is selected from an 8-hydroxyquinolate and a substituted 8-hydroxyquinolate, and Z is a phenolate. At least one Y is a substituted 8-hydroxyquinolate having the formula (III) where: R1 and R2 are the same or different at each occurrence and each represents one or more of a substituent selected from the group consisting of H, alkyl, fluoroalkyl, aryl, fluoroaryl, alkylaryl, alkoxy, aryloxy, fluoroalkoxy, fluoroaryloxy, heteroalkyl, fluoroheteroalkyl, heteroaryl, fluoroheteroaryl, heteroalkylaryl, heteroalkoxy, heteroaryloxy, fluoroheteroalkoxy, fluoroheteroaryloxy, a solvent- solubilizing group, and a Tg enhancing group, wherein at least one of R1 and R2 is a solvent-solubilizing or Tg enhancing group; and R3 is selected from the group consisting of H, an alkyl group, and a substituted alkyl group. |
